To open a Shadow Chest, the player will need a Shadow Key, which can open an unlimited amount of Shadow Chests without being consumed. Once a Shadow Chest is unlocked and emptied, it can be picked up after being broken down with a Pickaxe. Shadow Keys can be obtained from chests in the Dungeon, or rarely in underground chests. In the right lighting conditions, Shadow Chests may look like Golden Chests, this is often seen in The Underworld.
